-

i having simple kohana view, , javascript makes countdown of 30 minutes. hava put javascript file directory /media m , name countdown.js . problem is: how can call javascript? form view? or controller displayed in view? , how may address in controller or view js function or functions?

thank you

the countdown js:

var javascript_countdown = function () { var time_left = 10; //number of seconds countdown var output_element_id = 'javascript_countdown_time'; var keep_counting = 1; var no_time_left_message = 'no time left javascript countdown!';

function countdown() {     if(time_left < 2) {         keep_counting = 0;     }      time_left = time_left - 1; }  function add_leading_zero(n) {     if(n.tostring().length < 2) {         return '0' + n;     } else {         return n;     } }  function format_output() {     var hours, minutes, seconds;     seconds = time_left % 60;     minutes = math.floor(time_left / 60) % 60;     hours = math.floor(time_left / 3600);      seconds = add_leading_zero( seconds );     minutes = add_leading_zero( minutes );     hours = add_leading_zero( hours );      return hours + ':' + minutes + ':' + seconds; }  function show_time_left() {     document.getelementbyid(output_element_id).innerhtml = format_output();//time_left; }  function no_time_left() {     document.getelementbyid(output_element_id).innerhtml = no_time_left_message; }  return {     count: function () {         countdown();         show_time_left();     },     timer: function () {         javascript_countdown.count();          if(keep_counting) {             settimeout("javascript_countdown.timer();", 1000);         } else {             no_time_left();         }     },     init: function (t, element_id) {         time_left = t;         output_element_id = element_id;         javascript_countdown.timer();     } };

}();

//time countdown in seconds, , element id javascript_countdown.init(3673, 'javascript_countdown_time');

you can use kohana html helpers. in controller function or view file, can have :

echo html::script('media/countdown.js');

place echo statement after html element id "javascript_countdown_time". before closing </body> if possible.

... <div id="javascript_countdown_time"></div> ... <script src="/media/countdown.js"></script> </body>

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
